The California state rock is a beautiful blue green rock called Serpentine.  A diagonal belt of it runs across San Francisco from the old military base Presidio to the hills of Potrero near Starr King School and some magnificent Mariposa lilies.  Serpentine has a high concentration of Chromium and Cobalt – heavy metals.  It is also poor in nutrients such as nitrogen, phosphorus, and potassium.  It is a difficult substrate for many plants to live in.  However, some thrive in it. Image
